    Sales Dashboard Application for Windows Forms

    Shortly after the Q3 2009 release we developed the Sales Dashboard Application for Windows Forms - a composite business application for visualizing a company’s sales force performance. It is built with the Q3 2009 versions of Telerik’s WinForms components, RadChart for WPF, Telerik OpenAccess ORM, and implements the Telerik CAB Enabling Kit for WinForms, which helps in the development of smart-client line-of-business (LOB) applications. Since the interest in this application is still high, we felt the need to have a dedicated place to discuss this application. In case you have not played with it yet, download the source code, and enjoy!   Also check: Silverlight/WPF Sales...

    How To: Display RadGridView Row Details with RadWindow for Silverlight

    In one of my previous blog posts I have explained how to display hierarchical data with Row Details. Now, if you are familiar with Row Details features, you know that you are not limited to showing the details inside RadGridView. You can show them anywhere by using the handy external DetailsPresenter. As a matter of fact, each GridViewRow has one of those DetailsPresenter’s inside its template. So you will be using the same class that we are using internally to show the details of each single row. The documentation states that in order to display Row Details outside RadGridView, you need to place...

    Data-binding Telerik CoverFlow for Silverlight + some Routed Commands goodness

    With our still hot Q3 2009 release we introduced a brand new RadCoverFlow control, that was rewritten from scratch in order to be able to exploit some new features in Silverlight 3 that improved both its performance and appearance. We are now using matrix projections to transform the items’ content and pixel shader effects to render the reflection. This allows us to show and properly transform any element in RadCoverFlow, including UI Elements, controls and video, as well as instantly synchronize the reflection. This major change in the control caused major changes in its API and usage patterns. We provide some...

    Virtualized Telerik ComboBox for Silverlight

    In some scenarios it is required to load thousands of items in a ComboBox. Since by default the control creates RadComboBoxItem containers for each data item, it might take some time to open the drop-down. To resolve the problem you only need to change the RadComboBox ItemsPanel with VirtualizingStackPanel: <telerikInput:RadComboBox> <telerikInput:RadComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel /> </ItemsPanelTemplate> </telerikInput:RadComboBox.ItemsPanel> </telerikInput:RadComboBox> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   thus making the drop-down to open instantly. Attached is a simple application that loads 1000 items in two RadComboBox controls, one virtualized, the other – not virtualized. The difference between the two controls is visible and becomes much larger if you create 100,000 items! VirtualizingComboBox I hope this helps....
